The Facts About Melatonin and Healthy Sleep

Learn the facts about melatonin and how it can help regulate your sleep schedule. . Learn more at eVitamins, the largest online health Australia superstore.

Chances are you've heard of melatonin if you're having sleep problems and maybe even used it to help. If you haven't heard or even just want to know how it helps, we'd like to offer the full facts on this supplement. After all, melatonin is a pretty neat substance.

What is it?

In short: it helps the body relax so it can rest.

The longer version is that melatonin is a natural hormone produced naturally by our pineal gland when the sun goes down. It gets released into the bloodstream for around 12 hours to decrease alertness. If you've ever tossed and turned thinking about a million things at once, you can see how shutting down that part of your brain would help with getting some sleep. 

How To Use it

Short-term use of melatonin can help regulate your sleep pattern back into a healthy schedule. Other accounts, like taking it every night for years, studies have found to be caused by a placebo effect. That's when our body responds to something because we mentally think of the effects instead of actually experiencing them. That said, if taking a melatonin once in a while helps you get to sleep, it doesn't seem to matter if that's what's causing it or just a mental push to help you. You do you.

    Shop Smart

    Always talk to your doctor about the supplements you're taking and discuss with them before trying new ones, especially if you are on other forms of medication. Because there is no FDA regulation on melatonin, some supplements may contain more than the amount stated on the bottle. Purchase from brands you trust. Melatonin derived from animals may carry the risk of viral contamination so it's encouraged to purchase synthetic or lab-made.

    Sleep Tips

    You may be able to improve your sleeping patterns by making a few changes to your behavior and attitude towards sleep. We know it's hard - we work hard and love binge-watching too, but these tips are great to help you stay well rested. 

  • Keep a sleep schedule. Wake up and go to bed at the same time every day.
  • Monitor and restrict the amount of caffeine you consume during the day and at what time. Try cutting back on the coffee after the morning. Learn how to break the habit here.
  • Create a routine for getting ready for bed to help your mind relax and switch into "sleep mode".
  • Eliminate distractions in the bedroom. TV and computers should be turned off and monitor the temperature (it should be around 60 to 67 degrees). Use a separate alarm clock instead of your phone, if you can help it.
  • Exercise daily. It doesn't have to be hard exercise, a 30 minute walk will do. Just avoid physical activity before bed.
